Unfavorable Semicircle

In 2015, a YouTube channel called Unfavorable Semicircle started uploading tiny, four-second videos: a flat color, a single black dot, a voice saying “zero”… or “one.” By February 2016 it had uploaded around 72,000 of them. Then YouTube shut it down.

This is the story of how the internet tried to decode it, the hidden images people found inside its frames, and the 2022 posts that may finally explain what it was.
